Description

A kind of halogen-free expansion fire retardant functional agglomerate and preparation method thereof
One, technical field
The invention belongs to functional high polymer material field, specifically relate to a kind of halogen-free expansion fire retardant functional agglomerate and preparation method thereof.
Two, background technology
Halogen-free expansion fire retardant all adds in the plastics substrate with the powder state, and addition certainly will produce error in dipping after a little while; And addition can cause flying upward of dust again when big, worsens the production operation condition.A lot of plastics are to sell with pellet form, and both mix and are difficult for disperseing, and must bring difficulty to moulding, even influence quality product.
Fire-retardant master granule is a raw material with fire retardant, dispersion agent and the vector resin etc. of super quantity, makes through dispersion, mixing, plasticizing, granulation.With regard to assistant concentration in the plastics, master batch is various additives for plasticss " enriched materials "; Single with regard to fire-retardant for plastic, master batch is again " dilution " of fire retardant.
Patent about the preparation fire-retardant master granule is also a lot, but is to contain halogen fire-retardant master granule mostly, as the fire-retardant master granule based on antimonous oxide, is the fire retardant that contains the antimony base as CN200610012872.5, CN200710027466.0, brings very big pollution to environment.And present halogen-free flameproof master batch normally is matrix with the polyethylene, for acrylic resin PP is fire-retardant, may bring Effect on Performance, and the content of fire retardant is on the low side, does not often reach the effect of flame-retarded resin.
Three, summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of halogen-free expansion fire retardant functional agglomerate and preparation method thereof is provided.
In order to achieve the above object, the present invention is achieved through the following technical solutions: a kind of halogen-free expansion fire retardant functional agglomerate, its characteristics are: the halogen-free expansion fire retardant during this functional agglomerate is formed is a phosphorus-nitrogen expanding fire retardant, and matrix is polyolefin resin; Count by weight, this functional agglomerate consists of: halogen-free expansion fire retardant is 50~90 parts, and polyolefin resin is 20~45 parts, and compatilizer is 1~5 part, and 1~5 part of lubricant, surface treatment agent are 1~5 part;
Phosphorus-nitrogen expanding fire retardant among the present invention is the phosphorus-nitrogen expanding fire retardant or the Trinitarian macromole expansion type flame retardant of three sources coupling.
The expansion type flame retardant that the phosphorus-nitrogen expanding fire retardant of the three sources coupling among the present invention is made up of high-polymerization degree ammonium polyphosphate, tetramethylolmethane char-forming agent and trimeric cyanamide; The polymerization degree of described high-polymerization degree ammonium polyphosphate>1500.Trinitarian macromole expansion type flame retardant among the present invention is commercially available CN329 or Melabis macromole expansion type flame retardant; CN329 is the product of U.S. Great Lake company, and its chemical name is 2,4,8,10-four oxygen-3,9-hosphospiro [5,5] undecane-3,9-dioxy-3,9-two melamine salts, Melabis is the product of U.S. Borg-Warner chemical company, its chemical name be two (2,6,7-three oxygen-1-phosphorus-dicyclo [2,2,2] phosphoric acid ester melamine salt octane-1-oxygen methyl).
Consisting of of the phosphorus-nitrogen expanding fire retardant of the three sources coupling among the present invention: high-polymerization degree ammonium polyphosphate: tetramethylolmethane char-forming agent: the weight ratio of trimeric cyanamide is 40~70: 15~35%: 10~25%, and three's weight sum is 100%.
Polyolefin resin among the present invention is the general purpose polypropylene resin.
Compatilizer among the present invention is to be selected from a kind of arbitrarily in maleic anhydride grafted ethene-acetate ethylene copolymer, acrylic acid-grafted ethylene-vinyl acetate copolymer, maleic anhydride grafted polyethylene, acrylic acid-grafted polyethylene, maleic anhydride inoculated polypropylene or the acrylic acid-grafted polypropylene.
Lubricant among the present invention is to be selected from stearic acid, oxystearic acid, Palmiticacid, stearylamide, amine hydroxybenzene or the ethylene bis stearamide any one.
Surface treatment agent among the present invention is any one in the silane coupling agent.
Silane coupling agent among the present invention is to be selected from a kind of in tetrem thiazolinyl tetramethyl-ring tetrasiloxane, γ-(methacryloxypropyl) propyl trimethoxy silicane, vinyltriethoxysilane, vinyltrimethoxy silane, γ-(diethyl triamino) propyl trimethoxy silicane or the γ-An Bingjisanyiyangjiguiwan.
The preparation method of the halogen-free expansion fire retardant functional agglomerate among the present invention is: according to weight proportion, halogen-free expansion fire retardant, lubricant are put into kneader earlier to be mixed 5~7 minutes, add compatilizer, surface treatment agent and polyolefin resin restir more respectively 9~11 minutes, and made premix; Premix put into single screw pelletizer water-cooled is cut, granulation, packing, what promptly obtain high flame retardant content is the anti-flaming function master batch of matrix with the polyolefin resin.
Halogen-free expansion fire retardant functional agglomerate of the present invention compared with prior art has following advantage:
1, reduce energy consumption and production costs, simplified fire retardant and directly added COMPLEX MIXED operation in the resin, master batch only needs simple the mixing to get final product with resin.Can obviously reduce labor intensity, cut down the consumption of energy, reduce material loss, reduce production costs.
2, improve the order of accuarcy of fire retardant addition, before mixed with resin, the weighing master batch is littler than the error of weighing fire retardant, helps the accuracy of fire retardant metering.
3, master batch is made raw material and is adopted sealed mixing machine mixing, can prevent that powdery combustion inhibitor from flying upward.Powdery combustion inhibitor uses with mixed with resin after making master batch again, can obviously improve the production operation environment.
The present invention has fundamentally overcome the dust pollution of fire retardant, and fire-retardant master granule and polypropylene have good dispersiveness, and environmental protection is not polluted, and heavy metal content reaches general notary (SGS) report, and has good flame retardancy and very high economy.
